CEZ to invest CZK 48 million in repairs at Czech Dlouhé stráně pumped-storage plant this year

Energy company CEZ will invest CZK 48 million this year in repairs to the Dlouhé stráně pumped-storage hydropower plant in the Šumperk region. Most of the work was scheduled for a June and July outage, during which engineers shut down both generating units in turn. „The aim of this year’s repairs is to ensure the plant operates safely and reliably. In the coming years, we are planning a more extensive modernisation,“ Ludvík Štrobl, director of the Dlouhé stráně pumped-storage hydropower plant, told CTK today.

This year, technicians at the Dlouhé stráně plant repaired, among other things, spherical valves and turbine guide vanes. „We managed to paint the first section, about 100 metres long, of the water conduit for the first turbine-generator, and completed part of the electronic fire alarm system upgrade to improve protection and safety,“ Štrobl said. In addition to underground repairs, engineers also focused on work at other plant facilities. For example, they are building a new barrier to catch debris on the Česnekový potok stream above the lower reservoir and securing rocks on the slopes around the road leading to the upper reservoir. „The road is open to tourists and cyclists, but we recommend taking extra care,“ Štrobl added.
